DIAGNOSTIC TEST

  1. INTERMITTENT DTC WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in possible serious or fatal injury. The conditions necessary to set this DTC are not present at this time. Review the scan tool environmental data. If possible, try to duplicate the conditions under which the DTC set. If applicable, actuate the component with the scan tool. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors. Look for the data to change, the actuation to be interrupted, or for the DTC to reset during the wiggle test. Perform any Technical Service Bulletins (TSBs) that may apply. Turn the ignition off. Visually inspect the related wire harness. Disconnect all the related harness connectors. Look for any chafed, pierced, pinched, partially broken wires and broken, bent, pushed out, or corroded terminals. Perform a voltage drop test on the related circuits between the suspected component and the PCM. Inspect and clean all Powertrain Control Module (PCM), engine, and chassis grounds that are related to the most current DTC. If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits. For intermittent Misfire DTCs check for restrictions in the intake and exhaust system, proper installation of sensors, vacuum leaks, and binding components that are run by the accessory drive belt. Use the scan tool to perform a System Test if one applies to the component. A co-pilot, data recorder, and/or lab scope should be used to help diagnose intermittent conditions. Were any problems found during the above inspections? Yes Perform the necessary repairs. Perform the «PCM VERIFICATION TEST»(/jeep/grand-cherokee/wk2-2010-2013/remont/testing-diagnostics/#30l-diesel-intermittent-dtc-pcm-verification-test-pcmecmtcm-programming-pre-diagnostic-troubleshooting-procedure) .

  2. SPEED CONTROL VERIFICATION TEST Inspect the vehicle to make sure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary. With the scan tool, erase all DTCs. Road test the vehicle at a speed above 60 km/h (35 MPH). Turn the speed control ON/OFF switch on. Depress and release the SET switch. If the speed control does not engage, the repair is not complete, continue with step 12. Quickly depress and release the RESUME/ACCEL switch. If the vehicle speed does not increase by 3 km/h (2 MPH), the repair is not complete, continue with step 12. Using caution, depress and release the brake pedal. If the speed control does not disengage, the repair is not complete, continue with step 12. With the vehicle speed at least 60 km/h (35 MPH), depress the RESUME/ACCEL switch. If the speed control does not resume at the previously set speed, the repair is not complete, continue with step 12. Hold down the COAST switch. If the vehicle does not decelerate, the repair is not complete, continue with step 12. While still holding down the COAST switch, make sure the vehicle speed is at least 60 km/h (35 MPH) and release the COAST switch. If the vehicle does not adjust and set a new vehicle speed, the repair is not complete, continue with step 12. With the speed control engaged, depress the ON/OFF switch. If the speed control does not disengage, the repair is not complete, continue with step 12. If the vehicle did not successfully perform all of the previous steps, perform any Technical Service Bulletins (TSBs) that may relate to this condition, if necessary, return to the DTC List. If the vehicle successfully performed all of the previous steps, the speed control system is now functioning as designed. The repair is now complete. Are any DTCs or symptoms remaining? Yes Repair is not complete, perform the appropriate diagnostic procedure. No Repair is complete.
  3. CHARGING SYSTEM VERIFICATION TEST Inspect the vehicle to make sure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary. With the scan tool, erase all DTCs. Start the engine. Raise the engine speed to 2000 RPM for at least 30 seconds. Allow the engine to idle. Turn the ignition off for 20 seconds. Turn the ignition on. With the scan tool, read PCM DTCs. If this DTC has set again, or another DTC has set, perform any Technical Service Bulletins (TSBs) that may relate to this condition. Return to the DTC List if necessary. If the charging system is functioning correctly and there are no DTCs, the repair is now complete. Are any DTCs or symptoms remaining? Yes Repair is not complete, perform the appropriate diagnostic procedure. No Repair is complete.
  4. NO START VERIFICATION TEST NOTE: IMPORTANT! If the Wireless Control Module/Wireless Ignition Node has been replaced, make sure the programming procedure for the module has been performed in accordance with the service information. NOTE: If the Powertrain Control Module (PCM) has been replaced, Go to «SECTION 2 - ADDITIONAL PCM/ECM / TCM REPLACEMENT PROCEDURES»(/jeep/grand-cherokee/wk2-2010-2013/remont/testing-diagnostics/#30l-diesel-intermittent-dtc-pcm-verification-test-pcmecmtcm-programming-pre-diagnostic-troubleshooting-procedure__section-2-additional-pcmecm) of the PCM/PCM REPROGRAMMING, and perform the necessary routines. . Inspect the vehicle to make sure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary. Inspect the engine oil for contamination. If it is contaminated, change the oil and filter. With the scan tool, erase all DTCs. Turn the ignition off for at least 10 seconds. Attempt to start the engine. If the engine is unable to start, perform any Technical Service Bulletins (TSBs) that may relate to this condition. Return to the DTC List if necessary. If the engine starts and continues to run, the repair is now complete. Are any DTCs or symptoms remaining? Yes Repair is not complete, perform the appropriate diagnostic procedure. No Repair is complete.
  5. DTC/ROAD TEST VERIFICATION TEST Inspect the vehicle to make sure that all engine components are properly installed and connected. Reassemble and reconnect components as necessary. If this verification procedure is being performed after a non-DTC test, perform steps 3 and 4. If not, proceed to step 5. Check to see if the initial symptom still exists. If there are no trouble codes and the symptom no longer exists, the repair was successful and testing is now complete. If the initial or another symptom exists, the repair is not complete. Check all pertinent Technical Service Bulletins (TSBs) and return to the DTC List if necessary. For previously read DTCs that have not been dealt with, return to the DTC List and follow the diagnostic path for that DTC; otherwise, continue to step 6. If the Powertrain Control Module (PCM) has been replaced, Go to «SECTION 2 - ADDITIONAL PCM/ECM / TCM REPLACEMENT PROCEDURES»(/jeep/grand-cherokee/wk2-2010-2013/remont/testing-diagnostics/#30l-diesel-intermittent-dtc-pcm-verification-test-pcmecmtcm-programming-pre-diagnostic-troubleshooting-procedure__section-2-additional-pcmecm) of the PCM/PCM REPROGRAMMING, and perform the necessary routines. . Then continue to step 7. If equipped with a Transfer Case Position Switch, perform step 8, otherwise, continue with step 9. With the ignition switch on, place the Transfer Case Shift Lever in each gear position, stopping for 15 seconds in each position. With the scan tool, erase all diagnostic trouble codes (DTCs). Road test the vehicle. Drive the vehicle under various driving conditions. Attempt to duplicate the conditions in the Freeze Frame Data under which the DTC was set if possible. If this test is for an A/C Relay Control Circuit, drive the vehicle for at least five minutes with the A/C on. At some point, stop the vehicle and turn the engine off for at least 10 seconds, then restart the engine and continue driving. Upon completion of the road test, check for DTCs with the scan tool. If the repaired DTC has returned, the repair is not complete. Check for any related Technical Service Bulletins (TSBs) and return to the DTC List. If there are no DTCs, the repair was successful and is now complete. Are any DTCs or symptoms remaining? Yes Repair is not complete, perform the appropriate diagnostic procedure. No Repair is complete.
